Reflections on the European integration dimension.

This article discusses the importance of the issue of European integration on the study of political science within the European Union and dimensionality research. Topics include difficulties in the placement of moderate integrationist parties within a continuous European integration dimension, the differences between measurement approaches used to determine political party positions on integration, and an explanation of how EU integration position data becomes significantly less reliable from expert surveys, voter surveys, and European Parliament (EP) roll call votes when analyzed at limited sub-ranges.
